Cross Connection Control Program

Every drinking water system in Illinois must have a cross connection control program, more commonly known as a backflow prevention program. Backflow prevention is designed to protect the public water supply from contamination from non-drinkable sources. Cross-connection hazards exist in a variety of places, such as factories, processing plants, laundries, dental offices and hair salons. Residential in-ground sprinkler systems are also capable of contaminating the public drinking water if they are not properly protected. 

Backflow prevention devices are required on all commercial and residential properties where contamination hazards exist. These devices must be maintained and tested annually to ensure that they are working properly. The State of Illinois requires that every backflow device be inspected annually by a certified backflow tester, and every city that operates a public water system is responsible for making sure that this is done. 

The City of Naperville has contracted with Backflow Solutions Inc. (BSI) to manage the City’s backflow inspection program. BSI has experience managing similar programs for municipalities across the country, including many in the Chicago area. BSI will serve as the primary point of contact for backflow inspections within the City of Naperville and can be contacted at 800-414-4990 or through their website at www.bsiprograms.com

Water customers with previously registered backflow devices will receive a notification and reminder directly from BSI Online that testing is due. The customer is free to choose any licensed backflow tester they want. Once the annual inspection is complete, the licensed tester will enter that information directly into BSI’s online reporting system.
